Skiathos is the entry point and main island of the Sporades Islands. Although it is neither the biggest nor the most attractive of the Sporades islands, because it is the first port of call for most ferries and possesses the sole airport, most tourists don't venture beyond Skiathos. There are great beaches, good accommodation on offer, and decent public transport. In season, the 6,000 or so natives are vastly outnumbered by tourists from around the world.
It is undoubtedly the most tourist-intensive island of the Sporades, with beautiful scenery, quaint tavernas and lots of luscious green terrain great for strolling and hiking.
There is one town on Skiathos which is literally called "The Village" by the locals, or Skiathos town, on the east end of the island with the airport, port, and a variety of shops, bars and clubs on the waterfront.
